as said, i am wondering how to set up my second router to extend the service of my first one. i heard this was possible, help pls
Are you looking for an extender, or an access point? There's a difference.
An extender is WiFi in both directions.
Main router --- WiFi --- other router/Extender ---WiFi --- PC
An Access point is wired, and then WiFi
Main router --- Cat5e --- other router/Access Point --- WiFi --- PC
